We’ve talked about the manufacturing process of FIBC many times, including how to store them reasonably so that they can be used for a longer period of time. There are certain skills in these, including the FIBC produced by Yantai Zhensheng Plastics, which will be used when we go out. After strict testing, it will be delivered to the customer, so as to ensure that the customer's product will not be damaged due to the damage of the container during transportation. The following will tell you about the tensile test before the delivery of the container.
The raw materials of the container bag are all made of pp polypropylene environmental protection material. We have said before that this material is very similar to the polyethylene molecular structure, and the stability is high. This material can be used on large bags as long as it is processed. It's very easy to use. When we tested, we also tested under normal temperature.
After all, the temperature is too low or too high will affect the stretch of the bag, the tensile strength and elongation at break of the base fabric of the container bag The declining natural exposure has the most significant impact on the performance of the substrate. The anti-aging performance of the base fabric is closely related to the change of climatic conditions in the next high temperature environment, and the least significant under the low temperature environment. As the temperature rises, the light intensity increases, The deterioration of base fabric aging is based on the gray prediction theory to predict the natural aging mechanical properties of the FIBC base material. The prediction results have good accuracy, which can meet the requirements of engineering practice for the prediction accuracy of the natural aging performance of plastics, shorten the test time and save the test. cost.
The container bags that have passed the tensile test will be reused many times as long as they are properly stored and transported to the customer.
